1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

introductionThe aim of this study was to describe the clinical complications, treatment use, healthcare resource utilization (HCRU), and costs among patients with sickle cell disease (SCD) with recurrent vaso-occlusive crises (VOCs) in the US.

methodsMerative MarketScan Databases were used to identify patients with SCD with recurrent VOCs from March 1, 2010, to March 1, 2019. Inclusion criteria were ≥ 1 inpatient or  ≥ 2 outpatient claims for SCD and ≥ 2 VOCs per year in any 2 consecutive years after the first qualifying SCD diagnosis. Individuals without SCD in these databases were used as matched controls. Patients were followed for ≥ 12 months, from their second VOC in the 2nd year (index date) to the earliest of inpatient death, end of continuous enrollment in medical/pharmacy benefits, or March 1, 2020. Outcomes were assessed during follow-up.

resultsIn total, 3420 patients with SCD with recurrent VOCs and 16,722 matched controls were identified. Patients with SCD with recurrent VOCs had a mean of 5.0 VOCs (standard deviation [SD] = 6.0), 2.7 inpatient admissions (SD 2.9), and 5.0 emergency department visits (SD 8.0) per patient per year during follow-up. Compared to matched controls, patients with SCD with recurrent VOCs incurred higher annual ($67,282 vs. $4134) and lifetime ($3.8 million vs. $229,000 over 50 years) healthcare costs.

conclusionPatients with SCD with recurrent VOCs experience substantial clinical and economic burden driven by inpatient costs and frequent VOCs. There is a major unmet need for treatments that alleviate or eliminate clinical complications, including VOCs, and reduce healthcare costs in this patient population.
